The vehicle had 83,830 miles on the odometer at the time of the incident. The report was geocoded to Ohio based on the filer's self-reported location.

The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream.
